Why Michael trains

I'm all about pushing to get my best times! I love challenging myself with training and trying to break my previous records.

Run(317)

This is one of my favorite race series and I've been doing it for 10+ years. Run317 benefits different charities with each race and is a great way to support the Indy community!
